2 3 Claims.

This invention relates to, new and useful improvements in an indicator for electrical heat appliances.

This invention is a continuation of my application filed on September 4th, 1928, Serial No. 363,739 and bearing the samev title.

This invention has for an object the construction of an indicator for indicating when the appliance is in operation and mounted upon'an adjustable member for assuming various advantageous positions.

As another object of this invention it is proposed to mount the indicator within a recess formed in the appliance in a. manner so that it is capable of being extended or moved to a shielded position.

As a further object of this invention it is proposed to pivotally support a strip within a recess in the appliance and mount an indicator lamp upon the end of the strip and arrange a circuit including the winding of the appliance and the indicator lamp for the purpose previously set forth.

Furthermore, as another object of this invention, it is proposed to provide means for holding the strips in various pivoted and swivelled positions.

The invention has for a still further object the construction of a device of the class mentioned 1 which is of simple, durable construction, dependable in use and efficient in operation and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention,

-- and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:--

Fig. 1 is a perspective view of an electric iron with an indicator constructed according to this invention.

Fig. 2 is an elevational view of a toaster with an indicator constructed according to this invention.

Fig. 3 is an enlarged fragmentary sectional view of the body of the appliance through the recess in which the indicator is mounted.

Fig. 4 is a view similar to Fig. 3 but illustrating the device in a different position of adjustment.

Fig. 5 is an enlarged detailed view of a. portion of Fig. 3 showing in particular the swivelled con- .nection of the hinged strip.

Fig. 6 is a sectional view taken on the line 6-6 of Fig. 5. v

Fig. 7 is a fragmentary enlarged sectional view taken on the line 7-7 of Fig. 6.

In Fig. 1 an electric iron 10 has been illustrated which has a recess 11 formed in its body. In Fig. 2 a toaster 12 has been illustrated which also has a recess 11 formed in its body. Within each of these recesses the indicator, according to this invention, is mounted. The indicator in both cases, comprises a strip 13 hinged at one end 14 within the recess so as to be capable of pivoting upwardswith its'free end in various positions located from within the recess to exterior points. An indicator lamp 15 is mounted upon the free end of this strip and is connected in a circuit which includes the electrical winding 16 of the appliance. In the case of the electric iron, its heating winding, and likewise in the case of the toaster. In Fig. 3 leads 17 schematically illustrate the circuit.

The strip 13 is composed of a pair of sections 13 and 13 swivelly connected together. The

swivelled connection is accomplished by a tube 18. This tube is located between adjacent ends of the sections and each of the sections is formed with an opened portion 19 in the vicinity of the ends of the tube. One of the ends of the tube is formed with a head 20, While the other end is flared, indicated by reference numeral 21 so as to swivelly connect the sections. The indicating lamp 15 is mounted upon a socket 22 which in turn is attached on the free end of the strip 13. The circuit 17 electrically includes this socket.

A means is provided for holding the sections 13 and 13 in a swivelled position with either the socket 22 at the top or the bottom. Both of these positions are illustrated in Figs. 3 and 4. The means comprises resilient buttons 23 mounted upon one of these sections and engageable in niches 24 in the ends of the other section. These buttons are straddled on the sides of the tube 18. The resiliency of the button is accomplished by springs 25 housed within recesses and acting ios against the teeth of a serrated rack 30 which is bent in an arc coaxial with the pivot point of the strip. A projection 31 from the section 13 of the strip is engageable against one or another of recesses 32 located upon the section 13 so as to limit relative swivelling of the section through an arc of 180. The circuit 17 passes into the openings 19 in the sections of the strip 13 and through the tube 18.

In operation, when the appliance is working, the indicating lamp will be lit to call attention to this fact. Such indication will help to prevent accidental allowing of operation when the appliance is not in use. The strip 13 may be pivoted to various positions or may be swivelled with the indicating lamp directed downwards so that the light of indication may be directed as desired by the operator of the appliance. Thus the light may directly strike the eye of the observer or be shielded so that only reflected light reaches the observer.

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention what I claim as new, and desire to secure by United States Letters Patent is!- 1. An indicator for electrical heating appliances, comprising a recess formed in the body of said appliance, a strip hinged in the base of said recess so that its end may swing out, said strip being formed of sections swivelly connected with a tube, a lamp socket on the outer section, means for holding said strip in various hinged positions, and a circuit including said lamp socket and the electrical winding of said appliance and passing through said tube, the sections of said strip being formed with openings at the ends of the tube to allow the passage of the wires from said circuit.

2. An indicator for electrical heating appliances, comprising a recess formed in the body of said appliance, a strip hinged in the base of said recess so that its end may swing out, said strip being formed of sections swivelly connected with a tube, a lamp socket on the outer section, means for holding the outer section with the socket up or down, means for holding said strip in various hinged. positions, and a circuit including said lamp. socket and the electrical winding of said appliance and passing through said tube, the sections of said strip being formed with openings at the ends of the tube to allow the passage of the wires from said circuit.

3. An indicator for electrical heating appliances, comprising a recess formed in the body of said appliance, a strip hinged in the base of said recess, so that its end may swing out, said strip being formed of sections swivelly connected with a tube, a lamp socket on the outer section, means for holding the outer section with the socket up or down, means for holding said strip in various hinged positions, and a circuit including said lamp socket and the electrical winding of said appliance and passing through said tube, the sections of said strip being formed with openings at the ends of the tube to allow the passage of the wires from said circuit, said means for holding the outer section of said strip with its face up or down, comprises resilient buttons mounted upon one of the contacting ends of said strip and engaging with niches formed in the other of the contacting ends of said strips, the nicks and resilient buttons being located upon opposite sides of the swiveled connection and spaced equal distances, from said swiveled connection.
